Days ahead of the Nevada caucuses, Democratic presidential contender Hillary Clinton’s campaign released an emotional ad Thursday, titled “Brave.” It shows the former secretary of state comforting a young girl afraid over a deportation letter her family received. The one-minute ad shows mostly raw footage of the moving exchange, as Clinton assures the 10-year-old that she will fight on her behalf.

“I’m going to do everything I can so you don’t have to be scared,” Clinton said, after calling the girl to join her in the front. “Let me do the worrying. I’ll do all the worrying.”

The girl offers Clinton a hug as people sitting nearby wipe away their tears. The ad comes as Clinton and Vermont Sen. Bernie Sanders compete in Nevada for minority votes. In general, Clinton is seen to maintain a strong lead among Latinos and blacks, as she has made immigration reform a central part of her platform. She has proposed a plan for creating a pathway to citizenship for undocumented immigrants and has vowed to end family detention centers.

Thursday’s ad breaks from the frequent polished campaign advertisements, the New York Times notes. “Instead, she presents her realism with a hint of vulnerability, portraying herself as someone who understands the struggle, offering to worry and grasping the situation as only those close to this experience, or this fear, can," the newspaper said.

Clinton has in the past criticized Sanders for voting against immigration-reform legislation in 2007. Sanders said he opposed the guest worker program, which he said the Southern Poverty Law Center said was “akin to slavery.”

Clinton is expected to do well in states that are diverse, as she has routinely led in polling among black and Hispanic voters. Clinton held just a razor-thin lead over Sanders in Nevada ahead of the caucuses, 48-47, a CNN poll released Wednesday found. About 17 percent of Nevada's voters are Hispanic.
